No Post-Credits Scene in Age of Ultron?

One of my favorite things about seeing the Marvel movies is waiting around for the post-credits scene that teases what's coming up next for Marvel and/or the Avengers.

Well, don't get too excited about the end credits scene in Age of Ultron, because according to director Joss Whedon, there isn't one.

He wants fans to know now so we don't sit through ten minutes of credits just to get angry to find out there isn't one.

Does that count as a spoiler?  Well, it shouldn't, because I'm saving you guys ten minutes of your lives.
